Some cars have paddle shifters, and some cars have a gearbox with + and - . Is there a difference between these 2? Are they both equivalent to a fully manual transmission without having to use the clutch?

When I try to uncheck Kaspersky Internet Security and click "apply", the box just rechecks itself. I can successfully uncheck other programs, just not KIS. What could be wrong?

I'm thinking about using one of those motors above, and I need to attach a wooden disc to it. Is there something I can buy that will fit on the shaft of the motor and has screw holes for screwing something in? Or is there any other way I could attach a disc to those motors?

I need a motor to spin a breadboard at least 120rpm (the faster the better), and I need a way to attach the breadboard to this motor. I know I should probably get a PCB for this, but for what I'm doing, I need the whole thing in motion for testing. I'm not very experienced with electronics, so I don't know how to choose a motor, and I don't know how one generally goes about attaching things to a motor's shaft. Thanks for the help.

summation as n goes from 0 to infinity of cos(pi*n/2)*x^n/n!

The derivatives of cos(x) evauated at x=0 are 0, 1, 0, -1, 0, 1, etc. cos(pi*n/2) follows this pattern, if you start with n=0. But when I type the above into wolfram alpha, it doesn't give me the cosine function

I have a talk only plan with the unlimited domestic messages service. Will I be able to use email on my phone without paying extra? What about social buzz?

It's a simple box fan, and I need to get the speed of the wind. Any way I could do this?

For example, x^3-x^2-3x-6. All the elements of p/q (plus or minus 1, 2, 3, 6) aren't roots, so therefore there are no rational roots. Where do you begin solving this equation?

So, basically, I bought my computer, the warranty expired, and then a problem arose. I want to extend my warranty now. Will the problem be covered? It's a Lenovo, if that makes a difference

If anyone has this, can you tell me which firmware, which pops you're using, etc. Thanks

How much will it flow in relation to water, liquid soap, etc?

Or can I just use whatever regular ink I used to print photos and documents?

Most of my guitars have buttons that press down very easily, but my wireless guitar that came with GH:WT requires a lot of force to press the fret buttons. I've tried to play with it to "break it in" but after a few months of this it's still as bad as it was when I first got it. Any suggestions?

Is it possible to take AP Physics C while in a Trig/Analytic Geo/Precalc class? Or is there too much calculus in the course?

I'm looking for the torque applied by F1 about point P. I calculated the distance from P to the point of application of the force to be 1/2*L*sqrt(2). I calculated the perpendicular component of the force to be F1*sqrt(2), and multiplying them together I get F1*L, but I'm told the answer is 1/2F1*L. Where did I go wrong?

What is the velocity of the point at the top of the ball?

Please explain fully, thanks!
